Legacy data format

If sample data is generated from an S1 or S2C 802.15.4 XBee or an XBee 3 802.15.4 that has AO set to 2, the format of the sample data will be represented as a series of bytes in the following format which is compatible with the S1 802.15.4 and S2C 802.15.4 devices:

Bytes	Name	Description
1	Sample sets	Number of sample sets. This is determined by IT (Samples before TX) on the source node.
2	Digital and analog channel mask	Indicates which digital I/O and ADC lines have sampling enabled. Each bit corresponds to one digital I/O or ADC line on the device. bit 0 = DIO0 bit 1 = DIO1 bit 2 = DIO2 bit 3 = DIO3 bit 4 = DIO4 bit 5 = DIO5 bit 6 = DIO6 bit 7 = DIO7 bit 8 = DIO8 bit 9 = ADC0 bit 10 = ADC1 bit 11 = ADC2 bit 12 = ADC3 bit 13 = Reserved bit 14 = Reserved bit 15 = Reserved Example: a channel mask of 0x063C means ADC0, ADC1, DIO2, DIO3, and DIO5 are configured as digital inputs or outputs.
2	Digital data set	Each bit in the digital data set corresponds to a digital bit in the channel mask and indicates the state of the digital pin, whether high (1) or low (0). If the digital portion of the channel mask is 0, then these two bytes are omitted as no digital I/O lines are enabled. bit 0 = DIO0 bit 1 = DIO1 bit 2 = DIO2 bit 3 = DIO3 bit 4 = DIO4 bit 5 = DIO5 bit 6 = DIO6 bit 7 = DIO7 bit 8 = DIO8 bit 9 = N/A bit 10 = N/A bit 11 = N/A bit 12 = N/A bit 13 = N/A bit 14 = N/A bit 15 = N/A
2	Analog data set (multiple)	Each enabled ADC line in the analog portion of the channel mask has a separate 2-byte value based on the number of ADC inputs on the originating device. The data starts with AD0 and continues sequentially for each enabled analog input channel up to AD3. If the analog portion of the channel mask is 0, then no analog sample bytes are included.
